Simple Installer for BE based on NSIS

Hi all !
First I would like to thank all the contributers for this great peace of software !!

I wrote a small simple installer for BE ( which installs the source code not dll deployment .. )
This install script assumes that you have the latest version of NSIS + the time module

The installer assumes that you might have 3 different servers ... DEV , TEST , PROD , which you would have to configure in the ini file also pasted bellow ...

If somebody is interested to collaborate on the creation of full installers - both for production and development ( full meaning from configuring IIS and creating web site to creation of database + option to have separate installer for different database ,
please respond here ...

So here is the code ( there might be some bugs .. ) , Any comments ( even negative ones ; ) are appreciated !

;INFORM THE STARTING OF THE COPY
DetailPrint "Setting up the resource file for the server "
;COPY THE SERVER CONFIG FILES FOR THIS APPLICATION
;COPY THE SERVER FILE AS FROM SERVER.FILE TO FILE
;Delete the Web.config file from the development
Delete "$INSTDIR\Web.config"
;server = heitv156lab.devlab.nokia.com
DetailPrint "I saw CHOSENSERVER ${CHOSENSERVER} Followed by space"
CopyFiles "$INSTDIR\INSTALL\${CHOSENSERVER}.$R3.Web.config" "$INSTDIR\BlogEngine.Web\Web.config"
;${CHOSENSERVER}
;COPY THE App_GlobalResources folder
;Delete the App_GlobalResources from the development
;Delete "$INSTDIR\App_GlobalResources\*.*"
;Copy the server.app.App_GlobalResources to it's correct place
;CopyFiles "$INSTDIR\INSTALL\${CHOSENSERVER}.$R3.App_GlobalResources\*.*" "$INSTDIR\App_GlobalResources\"
;NOW DELETE THE INSTALL DIRECTORY CONTAINING THE DIFFERENT SETUP FILES
